Abstract
The utility model relates to a universal joint for a differential mechanism, and aims to provide a universal joint for a split type differential mechanism, which can be mounted without a special tool. The universal joint for the differential mechanism is characterized by comprising a long shaft and two short shafts, wherein two opposite insertion slots are arranged in the middle of the long shaft along the circumference; and plugs corresponding to the insertion slots in shapes are arranged at the ends of the short shafts. Preferably, the insertion slots in the long shaft are rectangular insertion slots; and the plugs on the short shafts are rectangular plugs. The long shaft is 150-300 mm long; and the shaft diameters of the long shaft and the short shafts are respectively 20-40 mm. The utility model also relates to the differential mechanism. The differential mechanism comprises a differential mechanism shell, the universal joint and a planetary gear connected with the universal joint, and the differential mechanism is characterized in that the universal joint is provided according to the utility model. The universal joint of the differential mechanism is of split type; no new accessory is added, and the special tool is also not needed; and therefore the labor cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of cross axle structure, particularly a kind of automobile differential cross axle, and the utility model also relates to a kind of differential mechanism of this cross axle of application.
Background technique
At present, common differential mechanism mostly is all-in-one-piece with the cross axle structure, mainly be because the restriction of former differential design, planetary pinion respectively accounts for half at the mounting spherical of differential carrier the inside in two and half shells the inside, two and half shells are processed sphere respectively, the differential carrier that processes like this, two very difficult assurances of concentricity that sphere lumps together; Differential carrier is processed as two and half shells and lumps together assembly processing cross shaft hole, and processing cost is higher.
The model utility content
At deficiency of the prior art, the utility model aims to provide a kind of split type differential mechanism cross axle that specialist tools is installed that need not.
In order to address the above problem, this kind differential mechanism cross axle is characterized in that comprising: a major axis and two minor axises, and this major axis middle part has two slots that are oppositely arranged along circumference, and the minor axis end has and the corresponding plug of slot shape.
Preferably, the slot on the described major axis is rectangular slot, and the plug on the described minor axis is rectangular insert.The length of described major axis is: 150mm～300mm; The diameter of axle of described major axis and minor axis is: 20mm～40mm.
The utility model also relates to a kind of differential mechanism, comprising: differential carrier, cross axle and the planetary pinion that is connected with cross axle is characterized in that: described cross axle is above-mentioned cross axle.
The beneficial effects of the utility model are: differential spider of the present utility model is split type, at first pack into having strong market potential in the poor shell, short pin is also packed into to stick into and is had strong market potential, have strong market potential and to fix, loaded onto by dynamic bevel gear at handle, short pin can also be fixed, and does not increase new parts, also need not to install with special tool, significantly reduced cost of labor.
Description of drawings
Fig. 1 is the structural representation of differential spider of the present utility model;
Fig. 2 is the structural representation of differential mechanism of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, this kind differential mechanism cross axle, it comprises: a major axis and two minor axises, this major axis middle part has two rectangular slot that are oppositely arranged along circumference, and the identical and end of two minor axis shapes has and the corresponding rectangular insert of slot shape.The length of described major axis is: 150mm～300mm, the diameter of axle of this major axis and minor axis is all between 20mm～40mm.
As shown in Figure 2, the utility model also relates to a kind of differential mechanism, comprising: differential carrier, above-mentioned split type cross axle and the planetary pinion that is connected with cross axle.
Cross axle of the present utility model is split type, during installation, at first big shell end differential gear and pad, planetary pinion and pad are put into by general location, earlier major axis are inserted in the differential casing, in the process of inserting from the planetary pinion pad, planetary pinion, planetary pinion, planetary pinion pad are put on successively, and then two short pins are inserted from the differential carrier cross shaft hole, pass the planetary pinion pad of its relevant position successively, planetary pinion, it is fixing to have strong market potential, and differential mechanism is installed with bolt again.Being pressed by dynamic bevel gear, short pin fixes again.
